Knowledge
The student who successfully completes the course will have the ability to understand the quantum properties of crystals ; will be able to demonstrate a solid knowledge of the mechanisms at the origin of the emission and absorption of light; will understand how electronic properties of the materials can be modified to obtain a wide spectrum of technological application; will be aware of the physical mechanisms behind the most popular applications of photonics such as LED and LASER; he will be able to understand how organic materials such as polymers can be exploited for applications in photonics.
Assessment criteria of knowledge
The student will receive a research paper on the topics of the course. Avoiding technical (experimental or theoretical) details, he will have to be able to understand the fundamental ideas of the work, which will be at the basis of some questions about related topics of the course
